IPC: B41F13/02
Filed: 1936-10-09
Abstract: 482,899. Printing-machines. WAITE & SAVILLE, Ltd., WHYTE, F. E., and WHYTE, F. Oct. 9, 1936, Nos. 27386/36 and 30696/37. [Class 100 (ii)] In a printing-machine wherein a paper web is intermittently printed between an upper die a and a lower impression member a<1> and is subsequently divided into sheets by cutting or perforating, the web-feeding and cutting mechanism is mounted so that it can be swung out of the machine about a vertical pivot when it is desired to feed sheets to the machine by hand. In one form, the web 2 is fed from a roll mounted near the rear of the machine by means of intermittently-rotated rollers driven by a chain 5d from other feedrollers 4a, 4b in front of the die a, the lower . one of which is actuated through a freewheel device on its shaft, a rack 6b, and a crank 6 on a shaft 7 driven by a belt 8 from the main shaft 9 through a releasable clutch 18. The upper roller 4b engages the margins only of the web. A cutting or perforating device 10 for dividing the printed web into sheets is operated from the shaft 7 through lever-mechanism 15, 16, 17. For varying the size of the sheets being printed and cut, the pivot of the rack 6b on the crank 6 is adjusted radially relatively to the shaft 7, and the carriage B<1> on which the cutting-devices are mounted is adjusted relatively to supporting brackets B by means of a screwed spindle 22. The feeding rollers 4a, 4b are also mounted on the brackets B which are pivoted to the side of the machine at b<1> in order that the web-feeding and cutting devices may be moved away from a central table D when it is desired to feed sheets manually to the machine. To permit of this movement, the rack 6b is lifted from engagement with the roller 4a and the belt 5d is removed. In a modified form the web-roll is mounted on the brackets B.

Abstract: 777,311. Supply meters. LANDIS & GYR. AKT.-GES.. Sept. 30, 1955 [Oct. 2, 1954], No. 27923/55. Class 37. [Also in Group XIX] Apparatus for indicating the vector sum of two quantities comprises two members adjustable in directions at right-angles to one another in accordance with the variables, one member 9 being movable on the other member 1 and carrying a pin 16, to which is anchored a traction element 18, tensioned by a weight 20 and guided over a measuring roller 19, whose axis of rotation is parallel to the plane in which the members 1, 9 move and which roller 19 is also arranged to be rotatable about an axis normal to that plane so that the traction element 18 turns the roller 19 in proportion to the length of the hypotenuse of the triangle established by the two quantities and adjusts the roller in thedirection of the hypotenuse. As shown, a measuring instrument 8 drives lead-screws 4, 5 to move a slide 1 while another instrument 14 drives a lead-screw 12 to move a nut 9 along guides 10, 11. In the zero position of the slide 1 and nut 9 the pin 17 on the latter lies immediately over the measuring roller 19 whose horizontal shaft is supported in a bearing cup 22 itself rotatable about a vertical axis. As the slide 1 and nut 9 move in accordance with the two quantities measured by the instruments 8, 14, the traction element 18 is drawn over the roller 19 rotating it in accordance with the magnitude of the vector sum, whilst turning the cup 22 through the vector angle #. Bevel gearing 23 passes this composite movement of the roller 19 to one sun-wheel 25 of a differential gear while gearing 27, 28, 29, 30, 31 turns the other sun-wheel in accordance with the vector angle only, whose magnitude may be indicated by a pointer 33 on a scale 34. Thus the planet wheel shaft 35 turns in accordance with the magnitude of the vector sum which is indicated by a pointer 37 on a scale 38. The traction element 18 may be a steel band tensioned by a weight 20 or by a coiled spring housed in the cup 22, the band may be perforated to engage pins on the roller 19, or the element may comprise two parallel steel wires co-operating with two discs in place of the roller 19. Cables and pulleys may replace lead-screws and nuts. The instruments 8, 14 for driving the slide 1 and nut 9 may be replaced by stepping mechanisms, servomotors or by hand-operated devices.

Title: Improvements in hot gas generators and in particular rocket motors
IPC: F02K9/72
Filed: 1963-07-16
Abstract: 1,040,183. Rocket motors. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES, O.N.E.R.A. July 16, 1963 [July 18, 1962], No. 28063/63. Heading F1J. [Also in Division F3] A gas generator or rocket motor has energy derived from the spontaneous reaction occurring between fluid and solid fuel components, the fluid being introduced into the motor by means of injection devices situated within the combustion chamber and the solid propellant forming a lining on the inside of the combustion chamber. The rocket motor comprises a combustion chamber 1 lined with two solid components 3a, 3b and has a stainless steel diaphragm 5 which creates turbulence within the flow stream while two sets of injector devices 6, 11 (Fig. 2, not shown) are provided for the introduction of nitric acid. The injectors 6 form two annular rows on a plate 7 which is the front end of the combustion chamber while the second set of injectors 11 is mounted downstream on the diaphragm 5. The acid is supplied via a valve 9, also used for starting and stopping the rocket motor, and the injectors 11 are fed by a conduit 12 and a toroidal shaped steel compartment 10 all of which are cooled by the incoming liquid. The injectors 11 may consist of a row of injectors directed either upstream, downstream or perpendicularly to the flow direction, or alternatively a cylindrical or conical sleeve with rows of holes emitting fluid in directions almost tangential to the sleeve. The relative rate of liquid delivered by the two injector devices is controlled by a sleeve 13 with suitably sized orifices affecting the supply to the conduit 12. Another embodiment (Fig. 6, not shown) shows a second diaphragm 5a supporting a third set of injection devices fed by a conduit located on the outside of the combustion chamber. A further embodiment (Fig. 10, not shown) shows a conical shape deflector 16 immediately downstream of the diaphragm 5 which deflects the liquid towards the solid layer 3b. The solid component 3a is designed to burn chiefly in the liquid phase and consists of 90% paratoluidine and 10% polyvinyl chloride by weight, while the component 3b burns chiefly in the gaseous phase and has proportions of 85% and 15% respectively.

Title: Improvements in methods of and apparatus for continuously determining quantitativelya given constituent of a mixture of gases
IPC: G01N7/08
Filed: 1926-11-08
Abstract: 271,027. Mase, R. P. May 15. 1926, [Convention date]. Gas analysis.-A constituent of a gas mixture is determined by producing a volumetrically constant flow of the mixture, removing the constituent therefrom, and causing the residual gas to flow through a constricted passage, the pressure difference on opposite sides of the constriction being indicated and serving as a measure of the proportion of the constituent present in the mixture. As shown, the mixture drawn in by a pump 2 passes first through a mechanical filter 3 and then through a chemical filter 4 which removes any impurity liable to vitiate the analysis. Any oil from the pump is removed by a filter 6, from which the mixture passes into a vessel 7 containing calcium chloride or strong sulphuric acid to remove all moisture, or water or dilute sulphuric acid to impart a definite humidity to the gas, the same condition of dryness &c. being restored by a vessel 35 before the final stage of the -process. Constancy of flow is ensured by forcing the gas mixture through 'a constriction 12 under constant pressure, the delivery pipe from the constriction communicating with a liquid reservoir 20 having a connection 19 to a vertical tube 16 into which dips a tube 23 branching from the main tube on the high-pressure, side of the constriction; the upper end of the tube 16 is open to the atmosphere. Adsorption of the constituent to be measured may be effected in a box packed with a solid reagent, or in a vertical tube 27, arranged so that the gas bubbles produce circulation of the liquid reagent through the tube and a reservoir 29. After restoration to its former condition of humidity &c., the gas escapes through the constricted orifice 37, the pressure being indicated on a manometer 38 or recorded bv a floatactuated instrument 40. If a second constituent is to be determined, the whole or a part of the gas passing through the constricted orifice 37 is conveyed to a second apparatus by a tube which communicates with one side of the manometer 38. The gases to be analyzed may be methane or carbon monoxide in mine gases oxygen or nitrogen in casing-head or natural gas, carbon monoxide or dioxide, or oxygen, in stack gases, &c. Carbon dioxide may be absorbed by causticsoda or potash solution or by soda-lime. Oxygen may be absorbed by alkaline pyrogallol solution or by combustion in an electric tube furnace. Methane may be removed by a hot catalyst such as platinum or an absorbent such as granular resin.

Abstract: 959,915. Recording mandibular movements. CULLEN BROS. Ltd. July 20, 1962, No. 28113/62. Headings A5K and A5R. [Also in Division G1] Apparatus for recording mandibular movements for indicating the flex ability and sensitivity of mouth opening and closing muscles comprises means to position a patient's skull and means to be secured to the patient's chin and connected to marking means for indicating relative movements of the upper and lower jaws, when the mouth is opened and closed. The patient's head is positioned by a forehead support 49 and a nose-supporting bar 54 which are adjustably but rigidly supported by a column 34 and a support 50, respectively, mounted on a base 10. A chin support member 42 is secured on the patient's chin by a band 43 and is articulated by a ball-and-socket joint 41 to a tubular member 40 which is telescopically arranged on one end of a rod 38. The rod 38 is vertically and horizontally pivoted on a ball-and-socket joint on the column 34. The rod carries a spring- loaded marking pen 39 which can be manually locked in retracted position or released to engage paper 24 disposed on a concave cylindrical surface 25 of a carriage 20. The axis of curvature of the surface passes through the pivot of the rod 38 so that as the patient opens and closes his mouth movements of the lower jaw are traced on the paper by the pen. The carriage is mounted on a threaded horizontal shaft 15 rotated by an electric motor 13 so that the carriage moves along the shaft between supporting brackets 12, 17. Switches 29, 31, 32 control the motor so that the carriage is moved continuously or intermittently as desired in either direction. Members on the carriage operate switches to cut-out the motor as the carriage approaches the limit of its movement in either direction. The base has a cut-away portion 11 to accommodate the patient's arm so that his head can be positioned laterally of the rod 38 for recording anteriorposterior movements of the lower jaw. In order that faults in the mandibular movements of the patient may be corrected an articulator comprising relatively pivotal upper and lower members 61, 62 carrying plaster casts of the patient's jaws and teeth is attached to the apparatus in place of the patient. The upper articulator member 61 is pivotal on the conical ends of adjustable screws 68 threaded in parts extending from the lower articulator member 62. A vertical rod 73 is adjustably clamped at the front of the upper member for adjusting the spacing between the members. The articulator is adjusted so that its recorded movements simulate the recorded mandibular movements of the patient. The plaster casts are then modified, e.g. by grinding to correct the movements of the articulator and such modifications may be subsequently applied to the patient.
